While there are plenty of rumors swirling around Nuance's presumptive major role in iOS 5, this app is not part of that mix. It's designed to work only as a microphone for the desktop apps.

The purported settings screenshots from iOS 5 that surfaced this weekend imply that on-device dictation powered by Nuance's code will be available as a system-level service on iOS devices, and that wouldn't require that users run a separate Nuance front-end app.
